ESA to Launch Comet Interceptor Mission in 2028

With Comet Interceptor, ESA plans to meet a comet on its first trip into the inner solar system. The mission was selected yesterday after a fast-track proposal process and will be developed on a rapid (for ESA) timeline, with a launch planned for 2028.

LightSail 2 Launch Viewing: Tips & Tricks

LightSail 2 is launching on the next SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy Space Center in Florida. It is one payload of many on the mission known collectively as STP-2. Space Test Program (STP) is a crucial part of the US Air Force’s development of advanced technologies in space.

Where We Are on 1 July 2019

The last quarter has seen few changes in the roster of planetary exploration spacecraft. SpaceIL’s lunar lander Beresheet is now on the lunar surface. Its descent on 11 April seemed to go nearly perfectly. Unfortunately, a cascade of events shortly before its planned landing caused it to hit the ground too fast, and it did not survive.

Treasure Hunting With Hayabusa2

IN THE EARLY hours of 22 February, light was just beginning to brighten the campus of JAXA’s Institute of Space and Astronautical Sciences (ISAS) in Kanagawa, Japan. It should have been a quiet time, but the Hayabusa2 control room was packed with people. We were about to land on an asteroid.

LightSail Launch Event

LightSail 2’s launch window opens on June 22, and we are finalizing plans for our launch viewing celebrations. Once we have finished coordinating the details with the Air Force’s STP-2 mission team and the Kennedy Space Center, we will share them with all of our members and backers so that you can join us in person or remotely via the internet.

Lunar Reconnaissance Orbiter Images Beresheet Impact Site

Lunar Reconnaissance Orbiter has successfully imaged the impact site of the Beresheet lander, which made a really good run at performing the first privately funded Moon landing on 11 April, but crashed after the failure of its main engine.

Chang’e-4 may have discovered material from the Moon’s mantle

The first science results from the unprecedented Chang’e-4 lunar far side mission are in. The mission’s Yutu-2 rover, deployed from the lander shortly after the Chang’e-4 landing on 3 January, has, with the help of the Queqiao relay satellite, returned data which suggests it has discovered material derived from the Moon’s mantle.

The Mars Exploration Rovers Update: The Final Report

It’s a fall afternoon at Endeavour Crater. The summer winds finally lost their energy and the dust storm season is over. But there are no more signals coming from Earth. No more comm sessions with the orbiters. Nothing like it used to be.

InSight Detects Some Very Small Marsquakes

InSight has finally detected its first Marsquakes, but so far, none have been large enough to produce good science. Still, it’s great news that the seismometer is producing sensible data.
