Scientists report that damage to the James Webb Space Telescope (JWST) caused by a micrometeoroid impact in late May 2022 may be more severe than previously believed.
A group of scientists evaluated the performance of the space telescope throughout its commissioning phase in a new report released last week following Webb’s amazing first photographs.
Tianwen-1 is a historic victory for both the CNSA and space exploration.
Upon successful orbital insertion and landing, Tianwen-1 became a historic victory for the CNSA and space exploration. Before Tianwen-1, the only two successful missions to send an orbiter and lander to Mars were NASA’s Viking 1 and 2 missions in 1975. Prior to that, the Soviet Union had attempted this feat with their Mars 2 and 3 missions in 1971 and Mars 6 in 1973.
Mars 2 was an outright failure, with the lander being destroyed and the orbiter sending back no data. On Mars 3, the orbiter obtained approximately eight months of data, and while the lander touched down safely, it only returned 20 seconds of data. On Mars 6, the orbiter produced data from an occultation experiment, but the lander failed on the descent.

We are stepping at the gates of a new era in space exploration, one which will finally incorporate the inner solar system to society’s daily life and economics. The first step is the Moon, and the asteroids will probably follow. The surface of those bodies presents special challenges for human and technological activities as well as resource exploitation. These challenges, which include regolith, extreme thermal amplitude, high energy radiation and surface mineral mixing among others, open the door to new operational approaches. COLMENA is the pathfinder of one such avenue: using swarms of micro-rovers for scientific exploration, resource prospection or, eventually, mining The first COLMENA mission will deploy 5 microrovers (56 grams each) on the Moon surface by the end of this year, flying on board a private spacecraft. In the talk I will briefly explain the context, technical characteristics and objectives of the mission, as well as its future.
A short bio.
Dr. Gustavo MEDINA TANCO is Professor at the Institute of Nuclear Sciences of UNAM in Mexico, where he leads the group of ultra-high energy cosmic rays and is the Head of the Laboratory for Space Instrumentation, LINX, which he created in 2009. He has also created, and is responsible for, the National Laboratory for Space Access (LANAE) in state of Hidalgo, Mexico, which will start operation in 2022. He was for 10 years the science coordinator of the International JEM-EUSO Collaboration and member of its executive board and, as such he lead the Mexican participation in the development of several instruments under the coordination of CNES, NASA, ASI and ROSCOSMOS.
