Margaret Hamilton
Ieri Margaret Hamilton ha ricevuto il prestigioso premio "Presidential medal of freedom" per aver guidato con successo il team per la creazione dell'on-board computer dell'Apollo 11, permettendo quindi il primo allunaggio umano della storia
Il codice scritto in linguaggio assembly che portò l'America sulla Luna nel '69 è stato pubblicato su GitHub. La routine di accensione dei motori principali si chiama BURN_BABY_BURN Girano altre routine di gestione dell'allunaggio, dove pare ci siano stringhe di indicazioni per gli astronauti "GIRARE QUEL COSO SCEMO LÌ" "CONTROLLARE SE DICE CAZZATE"
RIP John Glenn
New Horizons ha ufficialmente finito la sua missione primaria! L'ultimo bit di dati ottenuti durante il fly-by del 14 luglio 2015 è stato ricevuto dalla stazione di terra della NASA, a Canberra in Australia, martedì alle 11.48 ora italiana.
Questa sonda ha collezionato più di 50 GB di dati durante il suo paesaggio ravvicinato intorno a Plutone e Caronte e li ha inviati a terra impiegando poco più di un intero anno. La velocità di downlink è stata di 2'000 bit al secondo, una minuscola frazione rispetto alle connessioni a cui siamo abituati. Ora può iniziare la lunga fase di processing dei dati completi, che per adesso sono solo lunghe catene di 0 e 1.
Gli ingegneri di missione effettueranno un'ultima data review prima di cancellare definitivamente i dati sui due hard disk presenti a bordo della sonda, in vista delle nuove osservazioni scientifiche previste per il 2019. Il primo gennaio di quell'anno, infatti, New Horizons passerà a soli 3'000 km da 2014MU69, un antico corpo celeste presente ai confini del nostro sistema solare e scoperto due anni fa dal telescopio Hubble.
Nell'immagine potete vedere una delle scoperte più fresche del team di New Horizons: possibili nuvole intorno ai rilievi montuosi di Plutone.

IC1805 è una nebulosa diffusa in associazione ad un ammasso aperto, visibile nella costellazione di Cassiopea, verso il confine con la Giraffa. Fu scoperta nel 1787 da William Herschel ed è conosciuta come "Nebulosa Cuore".
Solar System: Things to Know This Week
10 Tools for the Armchair Astronaut, or How to Explore the Solar System from Home
At this very moment, spacecraft are surveying the solar system, from Mars, to Saturn, to Pluto and beyond. Now you can ride along to see the latest discoveries from deep space. For this week’s edition of 10 Things, we’ve assembled a toolkit of 10 essential resources for the desktop astronaut.
1. It’s Like Facebook, but for Planets
Or is it more of a Hitchhiker’s Guide to the Solar System? Whatever one calls it, our planets page offers quick rundowns, as well as in-depth guides, for all the major bodies in the solar system. Explore from the sun all the way to the Oort Cloud.
+ Peruse the planets + See how objects in the solar system stack up against each other
2. Keep Your Eyes on This One
If you still haven’t tried Eyes on the Solar System, you’re missing out. This free, downloadable simulation app lets you tour the planets and track the past, current and future positions of spacecraft–all in 3D. Eyes on the Solar System uses real NASA data to help you take a virtual flight across both space and time.
+ Prepare for departure
3. Dateline: Deep Space
With so much exploration underway, discoveries and new insights into the solar system come at a pace that borders on bewildering. NASA is rewriting the textbooks, literally, on a regular basis. Relax, though: there are several easy ways to stay up to date with what’s happening in space.
+ See the latest headlines + Stay connected on social media: Twitter, Facebook, Instagram + Find more top NASA social media accounts
4. Space? There’s an App for That
NASA offers phone and tablet apps for star gazing, pictures, news, 3D tours, satellite tracking, live NASA TV and many other kinds of info.
+ Start downloading + See other cool apps
5. A (Very) Long Distance Call
We’re in constant communication with spacecraft all over the solar system. The Deep Space Network is a global network of giant antenna dishes that makes it possible. With this online app, you can learn how it works – and even see which spacecraft are phoning home right now.
+ Deep Space Network (DSN) Now
6. Collect ‘Em All
Spacecraft 3D is an augmented reality (AR) application that lets you learn about and interact with a variety of spacecraft that are used to explore our solar system, study Earth and observe the universe. Print out the AR target and your camera will do the rest, making the spacecraft appear in 3D right in front of you. Learn more about these robotic explorers as they pop up on your desk, in your hand, or on your dog’s head.
+ Download Spacecraft 3D + See more cool 3-D resources from NASA
7. Ever Wanted to Drive a Mars Rover?
This site will give you a 3D look at the Mars Curiosity rover, along with some of the terrain it has explored. It will even let you take the controls.
+ Experience Curiosity
8. More E-Ticket Attractions
But wait, there’s more. NASA offers a variety of other fascinating (and free) online experiences, all based on actual data from real missions. Here are a few to explore:
+ Mars Trek + Vesta Trek + Moon Trek
9. The Universe Is Our Classroom
Studying the solar system makes for a compelling route into learning and teaching science, engineering and math. We have some great places to start.
+ Find resources for teachers + Build your own solar system with your classroom
10. Bring It on Home
After you’ve toured the far reaches of the solar system, you can always come home again. When you have spent time studying the harsh conditions on our neighboring planets, the charms of a unique paradise come into sharp focus, the place we call Earth.
+ Watch a real-time video feed from Earth orbit + See a daily global view of our planet from a million miles away + Hold the earth in your hands with the Earth Now mobile app

TODAY IN HISTORY: On October 18, 1989, the Galileo space probe launched from Cape Canaveral, Florida aboard the Space Shuttle Atlantis, heading out on a decade-plus mission to explore Jupiter and its neighbors. This early ‘80s NASA simulation footage shows how the spacecraft would eventually release a probe for a one-way trip into the turbulent Jovian atmosphere.
