Looking beyond Landsat 7
Monday, 07 June 2021 03:02
The land-observing satellite was supposed to work for five years. Now, more than 20 years later, Landsat 7 is still going strong.
In April 2021, the satellite marked its 22nd year of serving as a set of eyes on our home planet, documenting Earth’s splendors such as the expansion of cities and calamities like volcanic eruptions and historic wildfires.
US Air Force announces Fourth Vanguard Program

Since the era of meteorological satellites began in the 1950s, continuous remote sensing instrument improvements have elevated Earth science and have significantly increased available atmospheric observations. Likewise, scientists have made considerable advancements in understanding Earth's atmosphere, climate, and environment.
Furthering growth of atmospheric science within the last 20 ye Solar geoengineering may be effective in alleviating impacts of global warming on crops
Sunday, 06 June 2021 04:38
Solar geoengineering - putting aerosols into the atmosphere to reflect sunlight and reduce global warming - is not a fix-all for climate change but it could be one of several tools to manage climate risks. A growing body of research has explored the ability of solar geoengineering to reduce physical climate changes. But much less is known about how solar geoengineering could affect the ecosystem New study shines light on hazards of Earth's largest volcano

WASHINGTON — Lockheed Martin received a $1 billion contract to operate and maintain the ground control systems of the U.S. military’s Space Based Infrared System geostationary satellites, the U.S. Space Force announced June 4.
ExoMars rover twin begins Earth-based mission in 'Mars Terrain Simulator'
Saturday, 05 June 2021 09:05
The replica ExoMars rover that will be used in the Rover Operations Control Centre to support mission training and operations is fully assembled and has completed its first drive around the Mars Terrain Simulator at ALTEC, in Turin, Italy.
The rover 'Ground Test Model' (GTM) will play a critical role in the coming months as rover operators prepare for Rosalind Franklin's arrival in Oxia Pl A new water treatment technology could also help Mars explorers
Saturday, 05 June 2021 09:05
A team led by UC Riverside engineers has developed a catalyst to remove a dangerous chemical from water on Earth that could also make Martian soil safer for agriculture and help produce oxygen for human Mars explorers.
Perchlorate, a negative ion consisting of one chlorine atom bonded to four oxygen atoms, occurs naturally in some soils on Earth, and is especially abundant in Martian soil. NASA is returning to Venus

NASA has selected two missions, dubbed DAVINCI+ and VERITAS, to study the "lost habitable" world of Venus. Each mission will receive approximately US$500 million for development and both are expected to launch between 2028 and 2030.
It had long been thought there was no life on Venus, due to its extremely high temperatures. But late last year, scientists studying the planet's atmosphere an Did heat from impacts on asteroids provide the ingredients for life on Earth?
Saturday, 05 June 2021 09:05
A research group from Kobe University has demonstrated that the heat generated by the impact of a small astronomical body could enable aqueous alteration and organic solid formation to occur on the surface of an asteroid. They achieved this by first conducting high-velocity impact cratering experiments using an asteroid-like target material and measuring the post-impact heat distribution around Technique inspired by lace making could someday weave structures in space
