SpaceX launches Inmarsat-5 F4 satellite

SpaceX continued its busy launch campaign today with the successful delivery to orbit of the Inmarsat-5 F4 communications satellite.

The payload was originally planned to be launched using the companies Falcon Heavy Rocket due to the weight of the satellite. However, with the upgrades to the Falcon 9 over the years it is was powerful enough to perform the launch in expendable mode.

To date this is the heaviest payload SpaceX has ever launched, this meant that SpaceX didn’t attempt a landing instead letting the first stage splash down in the Atlantic Ocean after separation. SpaceX has another launch planned for June 1st to deliver another Dragon vehicle to the International Space Station.

SpaceX launches NROL-76 satellite

This morning SpaceX completed another important milestone in their history as they launched the first National Reconnaissance Office Payload the NROL-76 satellite.  As with all NROL launches the exact details of the payload and its final orbit were not released however Elon Musk tweeted that Launch and Landing of the payload were good if we get more information will update.  SpaceX once again brought the first stage back for a landing at Cape Canaveral Air Force Station (CCAFS) Landing Zone One.  As SpaceX was not allowed to show the second stage on the live stream they instead focused on the landing and returned absolutely amazing views of the stage as it returned to Earth, see the second video below.

With this launch, SpaceX has now broken the monopoly that United Launch Alliance had on NROL launches paving the way for more competition for future launches.

The launch was originally scheduled for Sunday 30th April but was scrubbed in the last few seconds due to a first stage sensor issue.

This was the fifth launch for SpaceX this year and the fourth landing, since the introduction of the Falcon 9 they have launched 33 times with one failure in 2015 and landed ten times, six of those on the Autonomous Spaceport Drone Ships.  SpaceX also suffered a failure during tanking operations for a Static Fire test, in both cases, they determined the most likely cause of the issue and came back stronger.

SpaceX has several more milestones they hope to achieve this year including the resumption of flights from CCAFS Launch Complex 40, the launch of the first Falcon Heavy, as well as the launch of the first Crewed Dragon vehicle.

SpaceX vs NASA progress since 2010

In 2010 Senator Richard Shelby made the following statement

“This request represents nothing more than a commercially-led, faith-based space program.  Today, the commercial providers that NASA has contracted with cannot even carry the trash back from the space station much less carry humans to or from space safely.

“These providers have yet to live up to the promises they have already made to the taxpayer.  Not a single rocket or ounce of cargo has been launched since we met last year.  Instead of requiring accountability from these companies, the President’s budget proposes to reward these failed commercial providers with an additional bailout.

While it was true at the time that no cargo had been launched by any of the competitors in the program, to say that SpaceX was a “failed provider that needed an additional bailout” seemed a little harsh. As we will see in the article things have changed quite a bit since then for SpaceX and for comparison in the same time frame we will see the lack of progress for NASA’s Space Launch System (SLS).

SpaceX

Started in 2002 by Elon Musk, Space Exploration Technologies Corporation known as SpaceX was created to lower the cost of access to space. The first rocket that was developed was the Falcon 1 which had a single Merlin engine, SpaceX attempted five launches of the Falcon 1 the first three of which failed. All their future hopes rested on the fourth launch which was successful and delivered their first payload to orbit, also making Falcon the first privately funded liquid fueled rocket to do so.

In 2006 SpaceX was awarded a NASA Commercial Orbital Transporation Service (COTS) contract which allowed them to develop the Falcon 9 rocket which is the vehicle they current use for all launches. Four years later SpaceX launched their first Falcon 9 rocket which carried the new Dragon cargo capsule to orbit for a brief mission that splashed down in the Pacific Ocean two orbits later, making SpaceX the first commercial company to successfully launch, orbit and return a cargo vehicle. Two years later they followed that launch with their first COTS demo mission to the International Space Station and soon after became the first and at present only commercial company capable of delivering cargo to and returning cargo from the station.

SpaceX didn’t stop with just NASA contracts, they so far launched XX commercial missions for various companies and has many more orders in their manifest.

Since that initial launch in 2010 SpaceX has upgraded the Falcon 9 rocket three times to what is currently in use today the Falcon 9 (v1.2) or Full Thrust version which is capable of carrying 22,800kg to Low Earth Orbit or 8,300kg to Geo-Transfer Orbit. SpaceX has also pursued a goal of making the Falcon 9 (and any future rockets) re-usable a goal which was achieved for the first time in March 2017.  There are two more upgrades planned for the Falcon 9 both of which are due in 2017, the changes should allow faster turn-around times for the reusability of the rocket and also address issues found with cracking in the Merlin engines.

In August 2012 SpaceX was awarded a second NASA contract this time to develop a crewed version of their Dragon capsule to allow NASA astronauts to be transported to/from the ISS.  They are still developing the crew version with a demonstration mission planned for late 2017.

Things haven’t been smooth sailing however in 2015 they suffer the first failure of their Falcon 9 vehicle when a strut broke during launch which caused the second stage to be destroyed, this resulted in the loss of a Dragon capsule carrying cargo to the ISS.  In 2016 during a static fire test, the rocket exploded on the launch pad resulting in the loss of the vehicle, its payload and significant damage to the launch pad.

Elon said after the successful SES-10 launch in March that so far SpaceX had spent about $1 billion dollars in the development of Falcon 9.  Some of that money came from NASA, some from the commercial launches and some from SpaceX themselves.

SLS/Orion

To put what SpaceX has achieved into perspective I thought it would be useful to compare what NASA has achieved in the same seven years since Senator Shelby made that statement.

The Space Launch System (SLS) started life as the Constellation program in 2005, the program was to consist of two launch vehicles Ares 1 and 5 as well as a crew capsule Orion.  This program launched a single Ares 1 rocket in October 2009 before it was canceled.  In 2010 under the direction of President Obama, the SLS program was launched utilizing the Orion capsule and a successor to the Ares 5 design.

Rather than develop a completely new system SLS was to be designed to utilize the RS-25 engines that flew on the Space Shuttle (STS) and upgraded versions of the Solid Rocket Booster that also launched STS. Unlike STS neither the engines or SRB’s are to be recovered after launch making SLS a completely expendable rocket.

Since 2010 NASA has spent approximately $18 billion dollars developing SLS and Orion and so far has only launched Orion once using a United Launch Alliance Delta Heavy rocket.  In addition, estimates show that each individual launch could cost anywhere from $500 million to $1 billion.

The current plan is for NASA to launch the first SLS rocket in 2018 on an uncrewed test, this schedule could be impacted however due to damage at NASA Michoud facility following a tornado.

While the first launch will prove the design of the SLS SRB’s, main stage and Orion capsule it will not allow a test of the complete system as it will use the Interim Cryogenic Propulsion Stage (ICPS) 2nd stage which is only going to be flown once.  The Exploration Upper Stage which will be used for subsequent launches is bigger than the ICPS, this will require that NASA makes changes to the mobile launch platform after one launch.

Recently NASA started an investigation into the possibility of adding a crew to the first mission, the results of this have not yet been published but could add additional delays.

Summary

In summary, since Senator Shelby made that statement SpaceX has launched 32 times include ten missions to the ISS, they have a large manifest of missions and have upgrades and new vehicles in development. Included in those missions is a plan to send the new Dragon spacecraft to orbit the Moon and also to land on Mars.

In contrast, NASA’s SLS system has cost approximately 18 times as much and so far only the Orion capsule has been launched. The first actual launch is still at least a year away and even then will not be the complete SLS system.  Until this year it could have been argued that SLS had different destinations in mind, however with SpaceX’s announcements of Red Dragon and more recently their Crew Dragon mission around the Moon this isn’t even a valid argument.

 

SpaceX makes history with SES-10 launch

Today SpaceX once again made history with the first launch of a previously flown first stage booster. The Falcon 9 lifted off at 6:27 pm EDT today with the SES-10 payload.

The booster was previously used for the SpaceX CRS-8 mission on 8th April 2016, the booster was the first to successfully land on an Autonomous Spaceport Drone Ship (ASDS). Following a comprehensive review of the booster, SpaceX was confident that it was ready for a second mission which it completed today with the successful launch and landing this time back on the ASDS “Of Course I Still Love You”.

During a press briefing after the successful mission, Elon Musk revealed that the payload fairing had been successfully recovered to making yet another milestone in the march towards rapid reusability.

The SES-10 payload was successfully deployed to orbit 32 minutes after liftoff making this the fourth successful mission of 2017.

SpaceX launches EchoStar 23

After several delays originally for the static fire test and then the weather SpaceX successfully completed its third launch of 2017 this morning with the delivery of the EchoStar 23 payload to orbit.  Liftoff occurred at 02:00 with the ignition of the nine Merlin 1D engines that propelled the towards orbit.  35 minutes later confirmation of payload separation was posted by SpaceX.

Due to the weight and destination of the payload there was no attempt to land the rocket either on land or the ASDS.

The full launch video from SpaceX is below, liftoff occurred at 12:00 minutes in.

SpaceX Moon Mission

In a stunning announcement yesterday SpaceX explained that two people had paid significant deposits for a Dragon 2 mission around the moon currently scheduled to launch in 2018.

Using a free return trajectory around the moon the mission will launch from KSC LC-39A atop a Falcon Heavy and then fly around the moon taking the crew further from Earth than any humans have ever been before.  The two crew members will spend seven days in space before returning to Earth either landing back in the ocean or potentially using a propulsive landing back on land.

Elon Musk made the announcement during a telecon that was announced on Sunday, he explained that SpaceX plans to launch the first uncrewed Dragon 2 later this year on a test mission to the International Space Station.  This new mission will not launch until SpaceX has completed the certification of Dragon 2 for NASA.

If SpaceX is able to achieve this schedule then they will do something that hasn’t been done since the last Apollo mission to the moon.  This will also leapfrog them over NASA which is currently looking into adding a crew to the EM-1 mission due to launch sometime in 2018, however it is likely to be delayed especially if they need to make changes to accommodate crew, otherwise the first crewed mission isn’t scheduled until No Earlier Than (NET) 2021.

SpaceX CRS-10 launches

This morning SpaceX made history once again as it made its first launch from Launch Complex 39A at Kennedy Space Center. The pad that had previously been used by NASA for Apollo and Space Shuttle launches has been refurbished by SpaceX over the last couple of years.

Designed to support the launch of Falcon Heavy, National Security Payloads and Crewed Missions 39A was called into duty following the September, 1st 2016 accident that resulted in the loss of LC-40 at neighboring Cape Canaveral.

The launch was originally scheduled to lift off yesterday but during to a 2nd Stage Thrust Vector issue they decided to scrub to allow time to investigate further.  The issue was resolved overnight and the countdown proceeded this morning to a 9:38 am EST launch when the nine merlin engines roared to life to propel the rocket to orbit.  Following completion of the first stage burn, the booster returned to Landing Zone 1 (LZ1) and landed making this the third time SpaceX has returned to LZ1.

SpaceX launches first of seven Iridium Next payloads

This afternoon SpaceX successfully returned to flight operations following the September 1st anomaly with the successful launch of ten Iridium Next satellites.  The launch was delayed several times due to the investigation into the anomaly, as well as the unfavorable weather around Vandenburg this week.

As a result of the investigation into the anomaly, there were several changes to the countdown process for this launch, the first and most obvious was the lack of payload during the static fire test.  Less obvious was the change to the fueling process in previous launches the RP-1 and LOX were loaded at the same time in the last 35 minutes of the countdown.  However for this launch the RP-1 loading started 70 minutes before launch with the LOX being loaded as before with 35 minutes left.

Following a smooth countdown the rocket lifted off on time and successfully deployed the ten satellites, however due to a ground station issue confirmation of the successful deployments took longer then expected.  The first stage also successfully landed on the ASDS in the pacific ocean.

 

Weekly Space News – 1/7

We are excited to bring back our weekly review of Space related news. These are a selection of stories that excite us about the future of Space exploration/development. The opinions in these reviews are our own.

NASA announces selection of two Discovery Missions

This week NASA announced that he has selected the Lucy and Psyche missions both designed to explore asteroids in our solar system.  Lucy due to launch in 2021 will visit a main belt asteroid in 2025 and then six Jupiter Trojan asteroids between 2027 and 2033.  Psyche due to launch in 2023 will visit 16 Psyche a giant metal asteroid, scientists believe it may have been the core of a planet which lost its outer layers.

SpaceX moves closer to return to flight

This week SpaceX completed the first Static Fire test since the September 1st anomaly that resulted in the loss of the Spacecom Amos 6 satellite and inflicted significant damage to Launch Complex 40 at Cape Canaveral.  Having concluded the investigation into the anomaly they determined that the most likely cause of the issue was due to the way the propellants were loaded into the rocket, full report here.  SpaceX has also received a launch license from the FAA allowing them to move towards a launch on Monday 9th from Vandenburg.

 

SpaceX ready for resumption of Falcon 9 launches

Following a four month investigation into the September 1st anomaly that resulted in the lose of a Falcon 9 rocket with it’s payload the Spacecom Amos 6 satellite and significant damage to Space Launch Complex 40 (SLC-40) at Cape Canaveral, Florida. SpaceX announced this week that they have completed the investigate (see report here) and are ready to return to flight operations started on Sunday 8th January with the first of seven launches for Iridium.

SpaceX are able to resume flight operations without having to make design changes to the rocket by changing their propellant loading operation to avoid the scenario that most likely caused the anomaly.  They have indicated that longer term they will make design changes to the COPV tanks to resolve the issue which will allow them to resume faster loading operations.

The flight of the Falcon 9 with ten Iridium Next satellites is currently scheduled for 10:28:97 PST on Sunday 8th January from Space Launch Complex 4E in Vandenberg, CA.  However this is still subject to the results of the Static Fire test scheduled for Tuesday 3rd and flight readiness review.
