Canadian firm builds satellites to track space trash
A Canadian startup plans to launch the first-ever commercial fleet of satellites designed to track dangerous space trash in 2022.
Montreal-based NorthStar Earth and Space has three of its Skylark satellites under construction for the new network, which eventually will number about 52 spacecraft.
The fleet would be the first of its kind to track space trash from space, rather than from gro Satellogic expanding U.S. footprint with eye on national security market
WASHINGTON — Earth observation company Satellogic is expanding its presence in the United States to compete in the government market. It is standing up a U.S. subsidiary specifically to work with national security agencies, Matthew Tirman, head of Satellogic North America, told SpaceNews.
China Satellite Navigation Conference to highlight spatiotemporal data
The 12th China Satellite Navigation Conference in 2021 (CSNC2021) will be held in May in Nanchang, east China's Jiangxi Province, highlighting the role of spatiotemporal data, according to the China Satellite Navigation Office.
The CSNC2021 will focus on the most recent technological and industrial application achievements of the BeiDou Navigation Satellite System (BDS) and development tre NASA data powers new USDA Soil Moisture Portal
Farmers, researchers, meteorologists and others now have access to high-resolution NASA data on soil moisture, thanks to a new tool developed by the U.S. Department of Agriculture (USDA)'s National Agricultural Statistics Service (NASS) in collaboration with NASA and George Mason University.
The tool, Crop Condition and Soil Moisture Analytics (Crop-CASMA), provides access to high-resoluti Rare meteorite recovered in UK after spectacular fireball
In a major event for UK science, the meteorite that fell from the fireball that lit up the sky over the UK and Northern Europe on Sunday 28 February, has been found.
Almost 300g of a very rare meteorite, known as a carbonaceous chondrite, survived its fiery passage through the Earth's atmosphere and landed on a driveway in the small Cotswold town of Winchcombe. Other pieces of this excepti Early Martian climate was intermittently warm
A new study that characterizes the climate of Mars over the planet's lifetime reveals that in its earliest history it was periodically warmed due to the input of greenhouse gases derived from volcanism and meteorites, yet remained relatively cold in the intervening periods, thus providing opportunities and challenges for any microbial life form that may have be Earth from Space: Strait of Gibraltar

WASHINGTON — NASA’s Hubble Space Telescope resumed observations March 11 after a software error placed it in a protective safe mode several days earlier, but the incident is a reminder of the telescope’s mortality.
NASA's Perseverance Mars rover mission honors Navajo language
Working with the Navajo Nation, the rover team has named features on Mars with words from the Navajo language.
The first scientific focus of NASA's Perseverance rover is a rock named "Máaz"—the Navajo word for "Mars." The rover's team, in collaboration with the Navajo Nation Office of the President and Vice President, has been naming features of scientific interest with words in the Navajo language.
Surface missions assign nicknames to landmarks to provide the mission's team members, which number in the thousands, a common way to refer to rocks, soils, and other geologic features of interest. Previous rover teams have named features after regions of geologic interest on Earth as well as people and places related to expeditions. Although the International Astronomical Union designates official names for planetary features, these informal names are used as reference points by the team.
