Hubble to search for New Horizons next target

When New Horizons was first launched towards Pluto the plan was for it to complete it’s mission and then fly on to another object in the Kuiper belt and perform the same observations as it does at Pluto.  The second destination has not yet been choose and researchers are now utilizing the power of the Hubble Space Telescope to aid the search.  While there is still plenty of time the science team will need to ensure they determined the orbit of the object so they can make any adjustments to the path of New Horizons once it leaves Pluto.

Messenger spots Space Weather effects at Mercury

NASA’s Messenger spacecraft currently in orbit of Mercury has allowed scientists for the first time to spot a hot flow anomaly or HFA.  A HFA is a classic space weather event which has been previous spotted at Venus, Earth, Mars and Saturn.

For more information on HFA’s and this detection check out the article here.

NASA Centennial Sample Return Challenge at WPI

Last week a number of teams took part in the NASA Centennial Sample Return Robot Challenge that was hosted by Worcester Polytechnic Institute (WPI) in Worcester, MA.

For this years challenge there were two levels available, the first level teams would compete for 30 minutes and had to return the designated sample to their starting platform with the robot operating complete autonomously.  Fourteen teams competed for this level with a single $5000 prize being awarded to the Mountaineers, first-time competitors from West Virginia University, Morgantown.

For the second level, teams had 2 hours to complete the challenge, this time they had to autonomously collect as many samples as they could during the allotted time with the prize money based on total weigh collected within the rules which can be found here.  This year there was only one team competing for this level, Team Survey who had completed level one last year, unfortunately due to a malfunction during start up of the robot they were not able to complete the challenge.  They did reboot the robot and performed a demonstration run on the course allowing them to collect very valuable data on the performance of the robot.

This was the third year of the competition hosted by WPI, next year Mountaineers and Team Survey will both be eligible for level 2 if they choose to compete.

Airbus and Safran join forces in Launcher market

Love them or hate them SpaceX are clearly making waves in the satellite launcher business, this is born out by the news this week that Airbus Group and Safran are further strengthening there relationship by creating a 50-50 joint venture to combine the launcher systems from Airbus and propulsion systems from Safran.

Massive Binary Stars more common than thought

Researchers in Chile have observed 800 celestial objects that are up to 100 times heavier than our Sun, and concluded that 90% turn out to be multiple systems.  Current telescopes do not have the power to see individual objects with a multiple system however so they can only go by the oscillation of the brightness of the object while being observed.

Coffee Machine heading to ISS

space-coffee-machine-isspressoAstronauts on the International Space Station (ISS) will soon be able to enjoy a freshly brewed coffee instead of the instant coffee they currently use.  The ISSpresso machine is a capsule based espresso machine built by coffee retailer Lavazza and aerospace company Argotec.  It is due to fly up to ISS later this year to coincide with the expedition of European Astronaut Samantha Cristoforetti who will not only be the first Italian woman in space but if all goes as planned by the first to enjoy a real Italian espresso in space.

Earth’s gravity causes Lunar bulges

For the first time scientists have been able to observe the bulge on the surface of the moon that is created by the gravitational pull of the Earth on the moon, using NASA satellites.  Due to the size of both the Earth and Moon they are in a gravitational tug-of-war which stretches both and causes them to have a slight oval shape.

On Earth we see the effects of this in the tides, however on the moon it is much harder as it is solid on the surface.  Careful observations of the surface have shown a 20 inch bulge on each side of the moon.  While the same side of the moon faces the earth this bulge does move around slightly due to the wobble of the moon during it’s orbit.

Are there large planets beyond Pluto?

The debate as to whether or not there are large planets beyond Pluto has been going on for decades and with the recent discovery of 2012 VP113 has revived interest in the subject.  Observations of extreme trans-Neptunian objects seems to indicate that they are being shepherded by a distant, undiscovered planet larger than Earth.

Gaia Space Telescope stray light problem

Astronomers for the European space observatory Gaia, which was launched last December have run into a problem with stray light entering the spacecraft.  This stray light will effect how well it can see the stars it is observing, the Astronomers stated that this would only effect the faintest of stars.  They also announced that the optics are not transmitting as efficiently as designed but that the amount of scientific data return will still be immense.

While one NASA probe whizzes by Saturn’s moon Titan on Thursday to analyze its atmosphere, the American space agency is also considering a plan to send a quadcopter drone capable of searching for life.

The ambitious idea was outlined by Larry Matthies, a research scientist and supervisor at NASA’s Jet Propulsion Lab in California, and involves a drone that would be capable of flying out of a lander or balloon. The drone would explore the moon’s landscape and seas, collect samples, and return to the “mothership” in order to recharge its batteries and submit whatever it collects for analysis.

Russian Dnepr rocket lofts record haul of 37 satellites

A Russian Dnepr rocket launched a record-breaking thirty-seven satellites on Friday morning local time, deploying a cluster of spacecraft for scientific research and commercial operation. The mission departed on schedule from Dombarovsky in Southern Russia at 01:11 local time (19:11 UTC on Thursday).

This launch saw the record for most spacecraft launched by a single rocket broken for the fourth time in less than a year.

NASA Announces Latest Progress, Upcoming Milestones in Hunt for Asteroids

NASA is on the hunt for an asteroid to capture with a robotic spacecraft, redirect to a stable orbit around the moon, and send astronauts to study in the 2020s — all on the agency’s human Path to Mars. Agency officials announced on Thursday recent progress to identify candidate asteroids for its Asteroid Redirect Mission (ARM), increase public participation in the search for asteroids, and advance the mission’s design.

NASA plans to launch the ARM robotic spacecraft in 2019 and will make a final choice of the asteroid for the mission about a year before the spacecraft launches. NASA is working on two concepts for the mission: the first is to fully capture a very small asteroid in open space, and the second is to collect a boulder-sized sample off of a much larger asteroid. Both concepts would require redirecting an asteroid less than 32 feet (10 meters) in size into the moon’s orbit. The agency will choose between these two concepts in late 2014 and further refine the mission’s design.

SpaceX Test Flight with Fins

This week SpaceX conducted another test flight of it’s F9R rocket, this time with deployable fins on the side of the rocket, these are designed to give the rocket more control during descent and is another step towards Elon Musk’s goal of having a fully re-usable Falcon 9 first stage.

No word yet when/if these will be flown on an actual Falcon 9 vehicle.

There may also be a possibility of testing the controlled descent on the Orbcomm flight scheduled for tonight.

SpaceX Launch later today (hopefully)

The Orbcomm OG2 launch has been rescheduled for later today, last Sunday’s attempt to scrapped to allow Orbcomm more time to verify their satellites were in a good configuration for launch.  The launch window starts of 6:08pm EDT and extends for 53 minutes.

At time of publishing the forecast shows only a 30% change that weather would co-operate, with a slightly better 60% tomorrow.  However the last launch had a low change of launching and they plugged away and got off the ground on time so there is a chance it will still go.

This week the Sierra Nevada Dream Chaser spacecraft completed a two hour captive carry test over Edwards Airforce base.  This was the first time that a fully operation version of the vehicle had flown and gave engineers the chance to review all systems before a series of approach and landing tests will be performed.  Initial tests will be fully automated before crewed tests are performed.

The Dream Chaser vehicle is one of three competing for the chance to launch US crews to the International Space Station.  Personally I hope there is a way to fund all three vehicles to give the US unprecedented access to space for the future.

 

Gaia spacecraft at launch site
