Artemis project aims to create a ‘sustained’ human presence on the moon by 2028

There can be no doubt that Nasa is serious about trying to land astronauts on the moon by 2024.

Even though the Artemis programme has yet to be fully funded, Nasa has issued a call to US companies for a lunar landing spacecraft that will place the first woman and the next man on the moon’s surface. The call has been sent out in draft form twice already this year, allowing private companies to comment and help Nasa shape the request. Now those companies have until 1 November to submit their finished proposals. From these, two companies will be contracted to provide the landers.

A NASA-created map that consolidated 26 different post-fire data sets can now do in minutes what used to take federal, state and local agencies 800 hours to compile. In 2018, a record year for fires, that saved those agencies the equivalent of more than $1.2 million dollars in staff time.

An online, post-fire decision support tool that quickly provides important information for response teams in the wake of a fire, the map shows where a fire's aftermath leaves an area vulnerable to debris flow, flooding, erosion and landslides.

The map is called Rehabilitation Capability Convergence for Ecosystem Recovery (RECOVER), and it's the brainchild of Keith Weber, an investigator supported by the NASA Earth Applied Sciences Disasters Program.

Before RECOVER, agencies could spend four to five days collecting, reviewing and analyzing fire data like burn severity, soil type and the slope of the land itself. Now, RECOVER incorporates all these data and dozens more (26 different layers in total) for users in one map – in as little as 5 minutes – meaning fire management agencies can better understand the reach and severity of a new fire, even as the blaze is still burning.

Released in 2013, RECOVER is an important tool in the fire managers’ toolbox, used more extensively in 2018 than in any previous year, particularly during California’s Woolsey fire.

In addition to recovery efforts, RECOVER's information is also important for first responders. If a landscape is too steep, it can become dangerous for firefighters to use trucks or bulldozers – instead, they have to proceed on foot. Now included in RECOVER is data from NASA’s Shuttle Radar Topography Mission (SRTM) on the slope of the land. It also includes soil type and measures of the “greenness” of plants, all factors that help wildfire response agencies understand how to safely recover from a fire.
