Reconstruction of second surface contact by Rosetta’s Philae lander during unplanned ‘hopping’ in November 2014 before its final ‘touchdown’.
The probe, rotating like a windmill, scraped a furrow in a highly porous, dark rocky area made of ice and dust on comet 67P, exposing 4.5-billion-year-old ice.
The ice has very weak internal cohesion and a consistency that is fluffier than cappuccino froth.
COLOGNE, Germany (DLR PR) — After years of detective work, scientists working on the European Space Agency (ESA) Rosetta mission have now been able to locate where the Philae lander made its second and penultimate contact with the surface of Comet 67P/Churyumov-Gerasimenko on 12 November 2014, before finally coming to a halt 30 metres away. This landing was monitored from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Philae Control Center.
Important milestone – successful completion of the 10th measurement campaign with the PK-4 plasma crystal laboratory on the ISS.
For the first time, the German Space Operations Center has taken over the scientific support of the PK experiments.
COVID-19 protection measures – DLR scientists from Oberpfaffenhofen maintain contact with the PK-4 Control Centre in Toulouse and the ISS.
Unique insights using PK-4 – plasma crystals can form in microgravity. The plasma particles behave like atoms and can be observed individually with the naked eye.
OBERFAFFENHOFEN, Germany (DLR PR) — Under normal circumstances, the researchers would have gone to Toulouse, as only from there can they control the PK-4 plasma crystal laboratory, which has been on board the International Space Station (ISS) since 2015. However, the Coronavirus pandemic has made travelling from Oberpfaffenhofen to the CADMOS Control Centre in France impossible. The experiments under microgravity conditions, which had taken months of preparation, were at risk of being cancelled.
Plasma research on the ISS – Cosmonaut Alexander Skvortsov will be carrying out a new series of experiments from 10 to 16 November 2019
Important knowledge for tomorrow – the plasma crystal laboratory PK-4 provides insights into fundamental physical processes
Plasma is ionised gas and is considered to be the fourth state of matter in addition to solids, liquids and gases. Complex plasmas are formed when dust particles are present in the neutral gas
TOULOUSE, France (DLR PR) — More plasma research is being conducted on the International Space Station (ISS). From 10 to 16 November 2019, the Russian cosmonaut Alexander Skvortsov will be carrying out a new series of experiments with the PK-4 plasma crystal laboratory. Under the direction of scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), Skvortsov will record how microparticles move through a neon plasma in microgravity, forming structures and thus providing insights into basic physical processes.
PASADENA, Calif. and ELISIUM PLANITIA, Mars (NASA/JPL-Caltech PR) — NASA’s InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA’s Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p.m. PST (8:30 p.m. EST). Solar array deployment ensures the spacecraft can recharge its batteries each day. Odyssey also relayed a pair of images showing InSight’s landing site.
PASADENA, Calif. and ELYSIUM PLANITIA, Mars (NASA/JPL-Caltech PR) — Mars has just received its newest robotic resident. NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander successfully touched down on the Red Planet after an almost seven-month, 300-million-mile (458-million-kilometer) journey from Earth.
InSight’s two-year mission will be to study the deep interior of Mars to learn how all celestial bodies with rocky surfaces, including Earth and the Moon, formed.
PASADENA, Calif. (NASA PR) — NASA’s Mars Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) spacecraft is on track for a soft touchdown on the surface of the Red Planet on Nov. 26, the Monday after Thanksgiving. But it’s not going to be a relaxing weekend of turkey leftovers, football and shopping for the InSight mission team. Engineers will be keeping a close eye on the stream of data indicating InSight’s health and trajectory, and monitoring Martian weather reports to figure out if the team needs to make any final adjustments in preparation for landing, only five days away.
