Webb measures temperature of rocky exoplanet for first time
The James Webb Space Telescope has measured the temperature of a rocky exoplanet for the first time, finding that a "cousin" of Earth most likely lacks an atmosphere, researchers said Monday.
When the Trappist-1 system was discovered in 2017, astronomers were excited at the prospect that some of its seven rocky planets - which are roughly similar to Earth in size and mass - could be habita Vatican to send Pope's message of hope into orbit
A message of faith and hope first delivered by Pope Francis in the middle of the 2020 coronavirus lockdown will be sent into space, the Vatican announced Monday.
The speech of the pontiff praying alone in an empty St Peter's Square have been turned into a "nanobook" measuring less than two millimeters wide, which will be launched into orbit on June 10.
It will travel around the Earth on a purpose-built satellite at an altitude of about 525 kilometers, dispatched on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.
The "Spei Satelles" (Satellites of Hope in Latin) project—whose cost and funding has not been revealed—is being coordinated by the Italian Space Agency in conjunction with various Italian institutions.
Agency president Giorgio Saccoccia said the Vatican had asked for "a solution that would allow the Holy Father's words of hope to cross the earth's borders and reach from space the greatest possible number of women and men on our troubled planet".
On March 27, 2020, the pope urged followers who felt "afraid and lost" in the face of what was then a terrifying new virus to have faith.
Webb space telescope measures the temperature of a rocky exoplanet
An international team of researchers has used the NASA/ESA/CSA James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI).
The result indicates that the planet's dayside has a temperature of about 500 Kelvin (roughly 230°C), and suggests that it has no significant atmosphere. This is the first detection of any form of light emitted by an exoplanet as small and as cool as the rocky planets in our own solar system.
Researchers find new water reservoir on moon
Lunar surface water has attracted much attention due to its potential for in-situ resource utilization by future lunar exploration missions and other space missions
Now, a research group led by Prof. Hu Sen from the Institute of Geology and Geophysics (IGG) of the Chinese Academy of Sciences (CAS) has found that impact glass beads in Chang'e-5 (CE5) lunar soils contain some water.
Detailed studies show that these glass beads are likely a new water reservoir on the moon, recording the dynamic ingress and egress of solar wind-derived water and acting as a buffer for the lunar surface water cycle.
This work was published in Nature Geoscience on March 27.
Many lunar missions have confirmed the presence of structural water or water ice on the moon. There is little doubt that most of the moon's surface harbors water, though the amount is much less than on Earth.

Council approves senior management changes
At its 315th session on 22 and 23 March 2023, the ESA Council approved a series of nominations and extensions of contracts for ESA directors:
Proba-3 complete: Formation-flying satellites fully integrated
The two spacecraft forming ESA’s Proba-3 mission for precise formation flying in orbit are now complete. All the instruments and sensors allowing them to manoeuvre to millimetre scale precision relative to one another have been integrated aboard, and the pair are fully wrapped in multi-layer insulation – ready to be tested in simulated space conditions.

Comtech validates 5G connection over satellite
Comtech has announced in collaboration with three global technology leaders: Cloud Signals, Hellas Sat, and a leading Mobile Network Operator (MNO), that the companies successfully tested and validated 5G connectivity over a satellite network in Greece.
During the demonstration, a commercial 5G node was connected to the leading MNO's 5G testbed network and relayed over a satellite link pro Dhruva and Kineis to offer satellite-based services
India-based full-stack space-engineering solutions provider Dhruva Space and France-based satellite operator and global connectivity provider Kineis have inked a Memorandum of Agreement (MoA), marking a partnership where both companies will collaborate to establish space and ground infrastructure to scale the diversity and impact of satellite-based solutions.
