DPS/EPSC update on New Horizons at the Pluto system and beyond
Last week's Division for Planetary Sciences/European Planetary Science Congress meeting was chock-full of science from New Horizons at Pluto.
Likely Schiaparelli crash site imaged by Mars Reconnaissance Orbiter
Just a day after the arrival of ExoMars Trace Gas Orbiter and its lander Schiaparelli, Mars Reconnaissance Orbiter has taken a photo of the landing site with its Context Camera, and things do not look good.
ExoMars: Schiaparelli Analysis to Continue
The fate of the ExoMars lander, Schiaparelli, remains uncertain. European Space Agency mission controllers had been optimistic on Wednesday night that a definitive answer would be known by Thursday morning’s news briefing. However, although some more details have been made public about the lander’s descent, it is not yet clear whether it hit the martian surface at a speed it could not survive.
DPS/EPSC update: 2007 OR10 has a moon!
The third-largest object known beyond Neptune, 2007 OR10, has a moon. The discovery was reported in a poster by Gábor Marton, Csaba Kiss, and Thomas Mueller at the joint meeting of the European Planetary Science Congress and the Division for Planetary Sciences of the American Astronomical Society (DPS/EPSC) on Monday.
Brief update: Opportunity's attempt to image Schiaparelli unsuccessful
Today, the Opportunity rover attempted a difficult, never-before-possible feat: to shoot a photo of an arriving Mars lander from the Martian surface. Unfortunately, that attempt seems not to have succeeded. Opportunity has now returned the images from the observation attempt, but Schiaparelli is not visible.
ExoMars: Long day’s journey into uncertainty
Trace Gas Orbit is successfully in orbit at Mars, but the fate of the Schiaparelli lander is uncertain.
Rapidly Rotating Regular Satellites and Tides
Pluto’s small moons have unusual rotation rates and states. Now we know a moon of another dwarf planet does as well. Is there a connection?
Juno to delay planned burn
The Juno mission posted a status report late Friday afternoon, indicating that they will not perform the originally planned period reduction maneuver during their next perijove (closest approach to Jupiter) on October 19. The delay changes the start date of the science mission and also all the future dates of Juno's perijoves.
ExoMars update: Timeline for separation and orbit insertion
Schiaparelli is GO for landing, and ExoMars TGO is GO for orbit insertion! When to expect ExoMars events: Schiaparelli separation, final trajectory maneuvers, landing events, orbit insertion, and press briefings.
Curiosity Update, sols 1428-1488: Through the Murray Buttes, drilling at Quela, and beyond
In the two months since my last Curiosity update, the rover has traversed the scenic Murray Buttes, drilled at Quela, and driven another 300 meters southward.
Alan Stern & New Horizons Team Receive Cosmos Award
Alan Stern and the New Horizons mission team are the newest recipients of The Planetary Society's Cosmos Award for Outstanding Public Presentation of Science.
ExoMars arrives soon!
ESA's ExoMars will arrive at Mars on Wednesday, October 19, with Schiaparelli touching down in Meridiani Planum, and the Trace Gas Orbiter entering orbit while Mars Express watches.
New Gems from the Moon
More than seven years after the end of its mission, JAXA has released the entire data set from Kaguya's HDTV cameras.
Fun with a new image data set: Mars Orbiter Mission's Mars Colour Camera
It's always a delight to sink my teeth into a new data set, and I have spent this week playing with one I've been anticipating for a long time: ISRO's Mars Orbiter's Mars Colour Camera, or MCC. MCC is unique among current Mars cameras in its ability to get color, print-quality, wide-angle, regional views of Mars.
MOM's Second Anniversary at Mars
On Mars Orbiter Mission’s second anniversary of Mars arrival, ISRO has (finally!) made available to the public data from its first year in orbit.
What's up in the solar system, October 2016 edition: ExoMars arrives!
ExoMars Trace Gas Orbiter arrives on October 19, and it will deliver the Schiaparelli lander to its brief life on the Martian surface. Juno's headed into its science orbit, MOM has released science data, and New Horizons will finally finish downlinking Pluto flyby data.
Mars Exploration Rovers Update: Opportunity Exits Marathon Valley then Rocks Spirit Mound
It was another September to remember for Opportunity as she cruised through the Lewis and Clark Gap and out of Marathon Valley, then hiked downslope, leading the first overland expedition of the Red Planet to Spirit Mound, a new site deep in Endeavour Crater’s rim.
Rosetta is gone
Today there is one less spacecraft returning science data from beyond Earth. The European Space Operations Centre received the final transmission from Rosetta at 11:19 September 30, UT.
OSIRIS-REx’s cameras see first light
As OSIRIS-REx speeds away from Earth, it’s been turning on and testing out its various engineering functions and science instruments. Proof of happy instrument status has come from several cameras, including the star tracker, MapCam, and StowCam.
Rosetta spacecraft may be dying, but Rosetta science will go on
The Rosetta mission will end tomorrow when the spacecraft impacts the comet. ESA took advantage of the presence of hundreds of members of the media to put on a showcase of Rosetta science. If there’s one thing I learned today from all the science presentations, it’s this: Rosetta data will be informing scientific work for decades to come.
