Intuitive Machines is one of several small companies that NASA has hired to transport instruments that will perform reconnaissance on the moon’s surface ahead of the return of NASA astronauts there, planned for later this decade.

At about 10 a.m. Eastern, the space agency will receive its first collected samples from an asteroid, delivered to Earth over the Utah desert.

NASA’s Perseverance rover has been diligently collecting rocky samples from Mars to stow them away on the planet’s dusty surface while engineers work to develop a rocket that can launch off of another world as a crucial step in the process of retrieving the samples.

Engineers from those groups formed the core of the Space Task Group (STG), NASA’s first official foray into space research, and Katherine, who had worked with many of them since coming to Langley, “came along with the program” as the NACA became NASA later that year. While not a member of the STG, she developed an interest in calculating trajectories of spacecraft and satellites.

It is always about the new The frontpage of any content-driven media is often geared towards the latest happenings. But what if there are old gems hidden beyond? A new user wouldn’t be able to discover them.

Comments are turned off.

The team expects dumping out the contents will be pretty straightforward, involving pointing the open end at the ground and letting gravity take over.

birnstiel commented on Mar 17, 2015 Thanks! The export script only returns the bibcodes, not the full entries. Is there a way to query all those bib codes? The ADS 2.0 search seems to support only one bibcode: search.

Solarsoft IDL

NOTE: the query part of URL (i.e., after "query?") is restricted to 1000 characters. This effectively limits the number of bibcodes you can specify in one query to about 40. The ADS API webpage mentions a "bigquery" alternative option, but I couldn't get this to work.

https://api.adsabs.harvard.edu/v1/search/query?bibcode=2015ApJ...799..218Y&fl=title However, it's necessary to specify your ADS key for this to work. With the Unix curl command, the query is: curl -H "Authorization: Bearer [KEY GOES HERE]" \\ "https://api.adsabs.harvard.edu/v1/search/query?bibcode=2015ApJ...799..218Y&fl=title"

APIs for Scholarly Resources What is an API? API stands for application programming interface. An API is a protocol that allows a user to query a resource and retrieve and download data in a machine-readable format.  Researchers sometimes use APIs to download collections of texts, such as scholarly journal articles, so they can perform automated text mining on the corpus they've downloaded. Here is a simple tutorial that explains what an API is.  Below are some APIs that are available to researchers. Some are open to the public, while others are available according to the terms of Temple University Libraries' subscriptions. Many require you to create an API key, which is a quick and free process.   How do I Use APIs? You can create a simple query in the address bar in a web browser. However, a more complex query generally requires using a programming language. Commonly used languages for querying APIs are Python and R. (R is the language used in the R software.) The examples given in the documentation for the APIs listed below typically do not include sample programming code; they only explain how the data is structured in order to help users write a query.

karnesky commented on Sep 1, 2013 A few things to note here: arXiv does have preprints, but a lot of these are linked to journal articles & some people use it as a reprint server. If an arXiv record has a DOI, I would suggest (strongly) that it should be typed as a journal article. We may even just use the ADS link, which seems to have a great BibTeX-formatted record for most eprints (though I'm torn on doing that). NASA ADS and most others classify arXiv eprints as journal articles anyway. Zotero will import any of those as journal articles, so there might be a case to import all arXiv eprints as if they were journal articles

According to the biblatex manual ftp://bay.uchicago.edu/CTAN/macros/latex/exptl/biblatex/doc/biblatex.pdf section 3.11.7, arxivprefix is an alias for eprinttype and primaryclass is an alias for eprintclass.

uses in general the fields archivePrefix, eprint and primaryClass

Adstex (Github, PyPI), written by Yao-Yuan Mao, allows you to bypass downloading BibTeX or other paper metadata to a master local database. Instead, you write your paper using TeX and cite commands as normal, then run adstex on the TeX document. The tool checks your paper for any cite commands, queries ADS, and downloads the necessary BibTeX entries to a .bib file for the paper.

For first author + year citation keys, by default adstex would only search the astronomy database on NASA ADS. However, you can use --include-physics to include the ADS physics database.

As it seeks answers about the cosmos and what they mean for Earth’s origins, NASA on Friday announced a slew of discoveries about Jupiter. And scientists brought home an interstellar tune from the road.

High-priority missions will continue, including a close encounter with a distant object called Ultima Thule, scheduled for 33 minutes past midnight on New Year’s Eve.

An asteroid more than a quarter mile (400 meters) wide will pass close to Earth on Wednesday, zooming by at a distance of just over a million miles (1.8 million km), but with no chance of impact, according to NASA scientists.

lesh, the engineering manager, and Dubusker drew on all of McDonnell's experience with shingled-skin structures around jet afterburners for heat protection.

Simulation tests indicate that manual control of the capsule attitude during retrograde firing will be a difficult task requiring much practice on the part of the pilot. By changing the command function from acceleration to rate, the task complexity will be greatly reduced and the developmental effort on display and controller characteristics can be reduced accordingly

There is a natural reluctance to relinquish the mechanical linkage to the solenoid valves but the redundant fly-by-wire systems offer mechanical simplification with regard to plumbing and valving hydrogen peroxide

"Using visible wavelengths of light, it is difficult to tell if an asteroid is big and dark, or bright and small, because both combinations reflect the same amount of light," said Carrie Nugent, a NEOWISE scientist at the Infrared Processing and Analysis Center at California Institute of Technology, in Pasadena. "But when you look at an asteroid in the infrared with NEOWISE, the amount of infrared light corresponds with how big the asteroid is, and with some thermal models on a computer, you can figure out how big the asteroids are."
