PARIS (ESA PR) — ESA’s new exoplanet mission, Cheops, has found a nearby planetary system to contain one of the hottest and most extreme extra-solar planets known to date: WASP-189 b. The finding, the very first from the mission, demonstrates Cheops’ unique ability to shed light on the Universe around us by revealing the secrets of these alien worlds.
Launched in December 2019, Cheops (the Characterising Exoplanet Satellite) is designed to observe nearby stars known to host planets. By ultra-precisely measuring changes in the levels of light coming from these systems as the planets orbit their stars, Cheops can initially characterise these planets — and, in turn, increase our understanding of how they form and evolve.
ESA’s Mars Express spacecraft has discovered several ponds of liquid water buried under the ice in the south polar region of Mars. The spacecraft’s radar instrument, MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding), revealed one underground reservoir in 2018, buried about 1.5 km below the ice. Now, taking into account more data and analysing it in a different way, three new ponds have been discovered. The largest underground lake measures about 20 x 30 km, and is surrounded by several smaller ponds. The water is thought to be very salty in order for it to remain liquid at cold temperatures.
Mars was once warmer and wetter with water flowing across the surface, much like early Earth. While it is not possible for water to remain stable on the surface today the new result opens the possibility that an entire system of ancient lakes might exist underground, perhaps millions or even billions of years old. They would be ideal locations to search for evidence of life on Mars, albeit very difficult to reach.
Subglacial lakes are also known on Earth, like Lake Vostok in Antarctica. They may harbour unique ecosystems, providing useful analogies for astrobiologists exploring how life can survive in extreme environments. The techniques used to analyse the radar data on Mars are similar to those used in investigations of subglacial lakes in Antarctica, Canada and Greenland.
China and Russia conducted launches on Sunday and Monday, placing five primary payloads and a group of rideshare satellites into orbit.
A Chinese Long March 4B booster lifted off from the Taiyuan Satellite Launch Center early Sunday morning. The three-stage rocket carried the Huanjing 2A and 2B environmental monitoring satellites into orbit.
Chinese media said the satellites will collect data for environmental protection, water conservancy, natural resources monitoring, agriculture and forestry. They will replace the Huanjing 1A and 1B environmental satellites launched in 2008.
On Monday, a Russian Soyuz rocket launched three Gonets M military communications satellites from the Plesetsk Cosmodrome. The rocket also included a group of international rideshare payloads.
WALLOPS, Va., Sept. 28, 2020 (Northrop Grumman PR) – Northrop Grumman Corporation (NYSE: NOC) is set to launch the company’s 14th resupply mission (NG-14) to the International Space Station under NASA’s Commercial Resupply Services-2 contract. The NG-14 mission’s Cygnus spacecraft will launch aboard the company’s Antares rocket with nearly 8,000 pounds (approximately 3,600 kg) of scientific research, supplies and hardware for the astronauts aboard the station.
KENNEDY SPACE CENTER (FL), September 28, 2020 – When Northrop Grumman launches its Cygnus spacecraft to the International Space Station (ISS) on its 14th commercial resupply services mission (CRS-14), it will do so with the eyes of children across the U.S. hoping to catch a glimpse of a rocket soaring into space.
Rocket launches have a unique ability to captivate audiences and inspire young students to look to the stars for inspiration. The upcoming resupply mission contracted through NASA, currently scheduled for launch no earlier than October 1 at 9:38 p.m. ET, will carry dozens of research experiments to the orbiting laboratory. However, these payloads are not just from professional researchers—multiple student experiments will also launch to the ISS on this mission.

On 2 July 2018, a £100 million satellite called CryoSat-2 was completing its daily rounds of monitoring ice caps back on Earth from an orbital vantage point 700 kilometres above us, when mission controllers spotted a chunk of space debris hurtling towards it at 17,000 miles per hour.
To avert a potentially catastrophic collision, engineers fired up CryoSat’s thrusters and moved it out of harm’s way. This near miss was not the first, and it will not be the last.
An estimated 20,000 pieces of space debris, better known as ‘space junk’; are whizzing around the Earth as you read this. This includes zombie satellites and whole junkyards’ worth of whirling fragments left over from space missions.
WASHINGTON (NASA PR) — Dragonfly is a NASA mission that delivers a rotorcraft to Saturn’s moon Titan to advance our search for the building blocks of life. While Dragonfly was originally scheduled to launch in 2026, NASA has requested the Dragonfly team pursue their alternative launch readiness date in 2027. No changes will be needed to the mission architecture to accommodate this new date, and launching at a later date will not affect Dragonfly’s science return or capabilities once at Titan.
COLOGNE, Germany (DLR PR) — The Chang’e-4 lunar lander touched down on the far side of the Moon on 3 January 2019, with a German instrument for measuring space radiation on board. Since then, the Lunar Lander Neutron and Dosimetry (LND) instrument has been measuring temporally resolved cosmic radiation for the first time.
On Thursday, a commercial Indian launch startup named Skyroot Aerospace unveiled its Dhawan-1 cryogenic engine to mark the 100th anniversary of Indian rocket pioneer Satish Dhawan.
The company said the engine is 100 percent 3D printed using additive manufacturing. It will be powered by liquified natural gas and liquid oxygen.
Satish Dhawan was an Indian aerospace engineer who was a pioneer experimental fluid dynamics research. He served as the third chairman of the Indian Space Research Organisation (ISRO). The nation’s spaceport is named after him.
Dhawan-1 will be used as the upper stage of Skyroot’s Vikram II booster. The company is developing three Vikram rockets to serve the small satellite launch market.
Vikrams will launch payloads ranging from 225 kg to 720 kg depending upon the rocket used and the orbit desired. Skyroot says the boosters can be assembled and launched within 24 to 72 hours with minimal infrastructure.
According to a story in the Economic Times, Skyroot was founded by three former ISRO employee who are looking to take advantage of India’s decision to allow private space companies to operate.
