  • Firefly Aerospace became the first commercial company to successfully achieve a soft landing on the moon on 2 March with the landing of Blue Ghost Mission 1 near Mons Latreille. It lasted the intended length of one lunar day before losing power on 16 March. It was launched with the Hakuto-R Mission 2 lander Resilience and rover Tenacious, which are planned to land in the Mare Frigoris.
  • On 6 March, the IM-2 mission's lunar lander Athena landed on Mons Mouton. Although intact, it landed sideways, preventing it from generating enough power to operate as designed. The mission was declared over the following day.
  • SpaceX Crew-9 splashed down near Tallahassee, Florida on 18 March. Initially planned to launch with a full complement, the extension of Barry Wilmore and Sunita Williams' stay on the ISS resulted in it being launched with only two crew members.
Article of the month

The Phootprint mission is a candidate for the Mars Robotic Exploration Preparation Programme 2 (MREP-2) at ESA. During 2014, ESA funded a pre-phase A feasibility study and industrial system studies of 8-month duration. Currently, it is in phase A, meaning 'mission definition study.'

The mission would last about 3.5 years, including cruise, mapping orbit, 7 days on the surface, and sample return cruise time. The spacecraft would be powered by solar arrays.

In August 2015, the ESA-Roscosmos working group on post-ExoMars cooperation, completed a joint study for a possible future Phobos Sample Return mission, and preliminary discussions were held.

InSight lander testing

The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander was selected from among three options in August 2012. Initially planned to launch in March 2016, an instrument issue delayed the launch to May 2018, the next Earth-Mars launch window. It was successfully launched on 5 May, and landed on Elysium Planitia on 26 November 2018. Taking seismographic and thermographic readings, InSight operated for a total of 4 years and 19 days instead of its planned 2 year mission. The mission was declared over on 21 December, 2022 after contact was lost on 15 December. A re-analysis of some of its data indicates that there may be significant amounts of groundwater in Mars' crust.

  • On 1 April, Fram2 became the first crewed mission to enter into a retrograde orbit around Earth's poles.
Article of the month

The Apollo Abort Guidance System (AGS, also known as Abort Guidance Section) was a backup computer system providing an abort capability in the event of failure of the Lunar Module's primary guidance system (Apollo PGNCS) during descent, ascent or rendezvous. As an abort system, it did not support guidance for a lunar landing.

The AGS was designed by TRW independently of the development of the Apollo Guidance Computer and PGNCS.

It was the first navigation system to use a strapdown Inertial Measurement Unit rather than a gimbaled gyrostabilized IMU (as used by PGNCS). Although not as accurate as the gimbaled IMU, it provided satisfactory accuracy with the help of the optical telescope and rendezvous radar. It was also lighter and smaller in size.

Falcon 9 Full Thrust

Starting development in 2014, the Falcon 9 Full Thrust is a variant of the Falcon 9 that is the first orbital rocket to have a first stage successfully land vertically after launch. The stage shown here is from the April 2016 SpaceX CRS-8 mission, after landing on the autonomous spaceport drone ship Of Course I Still Love You.
