Orbital ISS Launched Delayed again
The ORB-2 Cygnus cargo mission to the International Space Station (ISS) has been delayed again due to the on-going investigation into an AJ26 engine failure last month during testing. The Antares rocket which launches the Cygnus spacecraft uses two of the AJ26 engines on the first stage to orbit.
The new No Earlier Than (NET) date is July 1st, we will prove additional news when available on the launch date/time.
SLS design change could delay first crewed mission
NASA has decided to change the version of the second stage that will be used on the EM-2 crewed mission. Originally slated to be the Interim Cryogenic Propulsion Stage (ICPS) stage that will be used on EM-1 they have now elected to use the Exploration Upper Stage (EUS) stage that was originally scheduled to debut on EM-3. Due to this and the NASA Safety Office and Astronaut Office’s requirement that the upper stage complete at least one mission before any crew and be carried on it could mean that EM-3 becomes the first crewed mission for SLS in 2023.
An alternate option may be to add an additional flight between EM-1 and EM-2 which would be used to prove the EUS therefore allowing EM-2 to be the first crewed flight, however additional funding would be needed to achieve that. At present there are no future details as to the overall impact of the SLS schedule with primary focus on the EM-1 flight in 2017.
Progress M-21M undocks
This week the Progress M-21M spacecraft completed it’s mission to the ISS with a successful undocking and later burn up in the atmosphere. The cargo vehicle spent 144 days at the station having delivered almost 2,400 pounds of supplies it was then loaded with trash that was no longer needed. European Astronaut Alexander Gerst tweeted the picture below of the Progress burning up in the atmosphere to conclude it’s orbital mission.
The ESA Rosetta spacecraft completed two big burns this week as it entered the final phase of its approach to the Comet 67P/Churyumov-Gerasimenko after almost a decade journey. Unlike when it a spacecraft approaches a planet Rosetta will not be able to use the gravity of the comet to get into orbit but instead will need to execute a series of burns to precisely match the orbit.
It is currently approaching at a speed of 17,000 kpd (kilometers per day) and is currently less than 300,000 kilometers away. Over the next month and half it will continue to refine the orbit.
Two new exo-planets found around Kapteyn
A team of Astronomers have discovered two new planets around a nearby red dwarf star Kapteyn, which is about 13 light years away in the southern constellation of Pictor. One of the planets Kapteyn c is considered to be too cold for life because of it’s distance from the star. However Kapteyn b is within the habitable zone and therefore could have liquid water on the surface. The planet is estimated to be 5 times the mass of earth, and has an orbital period of 48 days.
Boeing CST-100 News
This week Boeing showcased their CST-100 spacecraft which is one of the spacecraft that is competing for the Commercial Crew contract to deliver astronauts to the ISS.
The spacecraft will be launched by an Atlas 5 rocket and once in orbit will dock to the space station to deliver up to seven people to the station. During the return the spacecraft will utilize airbags when it lands.
Boeing also indicated that further progress on the CST-100 would depend on them getting a contract from NASA in the CCtCap process which is currently on-going.
AAA Needed on Mars for Curiosity Rover
Originally expected to take a year to get to the base of Mt. Sharp the rover is currently half way there and clearly showing signs of damage from the un-yielding rocks as it moves over the surface.
Hmm wonder what the call out charge would be for AAA to replace the wheel, sign me up for that trip.
Russia plans Biggest Rocket since 1960s
The chief of the Federal Space Agency in Russia, Oleg Ostapenko said this week, while visiting Crimea, that they would need to build a super-heavy rocket capable of lifting between 80 to 85 tons to earth orbit in order to realize it’s lunar ambitions.
100 Million Planets may Harbor Complex Life in Milky Way
Scientists from the University of Texas have released findings based on the “first plausible assessment of complex life in the universe using empirical data.” The findings estimate that there could be as many as 100 million planets in our galaxy that may harbor some form of complex alien life. The article also says that our galaxy is one of approximately 500 billion in the universe.
Author Note: The estimate of galaxies in this article seems to be very high a factor of 2.5-5 times higher than most other articles or current estimates.
Trillion Dollar Market
This week Planetary Resources released a video, explaining why they believe fuel from asteroids will create a Trillion Dollar market in the future. Currently satellite operators have to pay for total weight of the spacecraft, including any fuel needed for the life of vehicle.
Smoke detected on ISS Tuesday, crew were not in danger
This week smoke was detected on the ISS, in the Zvezda Service Module, requiring flight controllers to initiate emergency procedures to isolate the modules ventilation system while the source of the some was identified. The crew were never in any danger and the problem was quickly determined to be a heater that was used for water reclamation. The heater was deactivated, a fan and filter was then setup to clear the smoke.
Kepler Candidate List updated
The NASA Kepler project updated the number of Kepler candidates and confirmed planets from 3,845 to 4,254. There are now up to one hundred potentially habitable worlds in the Kepler candidates, 30 matching the conservative definition of a potentially habitable.
Pluto and Charon news
Pluto has often been considered a binary planet with its largest moon Charon, it now seems that they may both also share a thin atmosphere. While it is impossible to detect the atmosphere using ground based technology the New Horizon’s spacecraft that is current racing towards Pluto will have the ability to detect it.
We will know more in 2015 after the flyby has been completed and the data is back on earth.
In a separate article researchers suggest that if cracks are found in the surface of Pluto that could indicate that the interior was once warm enough to sustain an underground ocean.
Dream Chaser News
Sierra Nevada Corporation who are building the Dream Chaser spacecraft that is competing for the contract to fly astronauts to the ISS this week announced a new partnership with Craig Technologies, a Cape Canaveral based company. The company will be responsible for the design engineering and manufacture of Dream Chaser.
3D Printer heading to ISS on next SpaceX mission
The 3D Printer developed by Made In Space has passed the final certification by NASA and will now be launched to the ISS on the next SpaceX mission in August. The printer was originally planned to launch on the SpaceX 5 mission but having completed all the milestones needed ahead of schedule they will now only need to wait until then to see the printer in action.
Once on the station a series of tests will be run to verify the ability to created printed parts in a micro-gravity environment.
Rumor: Google and Virgin Galactic in talks
England’s Sky News has reported that Google and Virgin Galactic have been in talks for months regarding a potential investment by Google. While no deal has been finalized it is believe to be a part of Google plans to launch a fleet of satellites to provide Internet access to the whole planet.
SpaceX’s Orbcomm Launch delayed again
The launch of six Orbcomm satellites on a Falcon 9 has been delayed again, originally scheduled for Thursday this week after previous delays the date was changed to Sunday after a problem was found with one of the satellites.
While the problem with the satellite appears to have been resolved Orbcomm have decided to perform additional testing to verify the issue has been fully addressed. In order to complete the analysis the June 15 launch date is no longer achievable and they are working with SpaceX to identify a new launch date.
