A space suit or spacesuit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. Space suits have been worn for such work in Earth orbit, on the surface of the Moon, and en route back to Earth from the Moon. Modern space suits augment the basic pressure garment with a complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum. A self-contained oxygen supply and environmental control system is frequently employed to allow complete freedom of movement, independent of the spacecraft.
Three types of space suits exist for different purposes: IVA (intravehicular activity), EVA (extravehicular activity), and IEVA (intra/extravehicular activity). IVA suits are meant to be worn inside a pressurized spacecraft, and are therefore lighter and more comfortable. IEVA suits are meant for use inside and outside the spacecraft, such as the Gemini G4C suit. They include more protection from the harsh conditions of space, such as protection from micrometeoroids and extreme temperature change. EVA suits, such as the EMU, are used outside spacecraft, for either planetary exploration or spacewalks. They must protect the wearer against all conditions of space, as well as provide mobility and functionality.Some of these requirements also apply to pressure suits worn for other specialized tasks, such as high-altitude reconnaissance flight. At altitudes above the Armstrong limit, around 19,000 m (62,000 ft), water boils at body temperature and pressurized suits are needed.
The first full-pressure suits for use at extreme altitudes were designed by individual inventors as early as the 1930s. The first space suit worn by a human in space was the Soviet SK-1 suit worn by Yuri Gagarin in 1961.

Recently discovered asteroid 2023 DW has been predicted to have a close encounter with Earth on Feb. 14, 2046. See NASA's current odds of impact along with an orbit animation. 

The space rock is estimated to be about 50 meters (164 ft) in diameter.

2023 DW is a near-Earth asteroid of the Aten group. It is approximately 50 meters (160 feet) in diameter, roughly the size of the asteroid that caused the Tunguska event, and was discovered by Georges Attard and Alain Maury, from the MAP (Maury/Attard/Parrott) asteroid search program in San Pedro de Atacama on 26 February 2023, when it was 0.07 AU (10 million km) from Earth.  On 28 February 2023, with an observation arc of 1.2 days, it was rated 1 on the Torino scale for a virtual impactor on 14 February 2046 at 21:36 UTC. The nominal approach is expected to occur about five hours before the impact scenario at 14 February 2046 16:57 ± 1.2 days. With a Palermo scale rating of –2.12, the odds of impact are about 132 times less than the background hazard level. The asteroid has not been observed since 4 March. By 5 March, the asteroid had become more difficult to observe as it was within 30 degrees of the waxing gibbous moon.It came to perihelion (closest approach to the Sun) on 26 November 2022, and then approached Earth from the direction of the Sun making closest Earth approach on 18 February 2023 at distance of about 8.7 million km.

Lyssna på tre minuter om ODIN-modellen med vår analytiker Carolina Elvind. För att identifiera de bästa investeringsmöjligheterna analyserar vi alltid alla potentiella investeringar på samma sätt. Vår analys består i huvudsak av tre delar – prestation, position och pris.

Prestation - Hur framgångsrikt har företaget varit på att skapa värde över tid?
Position - Kommer de förutsättningar som är avgörande för företagets konkurrenskraft att finnas kvar?
Pris - Hur är företagets verkliga värde jämför med marknadsvärdet?

Vi är en långsiktig investerare och vi spenderar mycket tid och resurser på att vara en ansvarsfull ägare. Vi väljer aktivt och väljer också aktivt bort utifrån ODIN-modellen, vår beprövade investeringsmodell. Vi tittar inte på månad för månad utan över betydligt längre tidsperioder.

Som engagerade ägare har vi en tät kontakt med ledningen för de företag vi investerar i. För oss är det viktigt med en aktiv och öppen dialog om att ha en hållbar verksamhet. Exempelvis i mindre företag kommer vår röst som ansvarig förvaltare att väga tyngre eftersom vår andel i företaget är större. Detta gör det lättare för oss att få igenom viktiga förändringar som är i andelsägarnas intresse och som gör oss till stolta ägare.

Vårt engagemang som ägare är främst för att bidra till företagens långsiktiga värdeskapande. Det kräver att de bedriver sin verksamhet på ett hållbart sätt på sikt och att företagsledningen har förmåga och vilja att prioritera långsiktigt värdeskapande.

Esrange Space Center är Sveriges enda rymdbas. Anläggningen ägs av Swedish Space Corporation (SSC).
Esrange är beläget cirka 40 kilometer öster om Kiruna. Några av anledningarna till att basen ligger just i Kiruna är att området i stort sett saknar ljusföroreningar och att man kan studera norrsken samt att området är glest befolkat. Man har, genom forskning på Esrange, lyckats förstå mer om norrsken och hur det uppstår. Rymdstationens markområde omfattar 20 kvadratkilometer, nedslagsområdet för raketer 5 600 km². 2016 sköts tio obemannade raketer upp och man släppte upp 24 höghöjdsballonger från Esrange.

Orion (officially Orion Multi-Purpose Crew Vehicle or Orion MPCV) is a partially reusable crewed spacecraft used in NASA's Artemis program. The spacecraft consists of a Crew Module (CM) space capsule designed by Lockheed Martin and the European Service Module (ESM) manufactured by Airbus Defence and Space. Capable of supporting a crew of six beyond low Earth orbit, Orion can last up to 21 days undocked and up to six months docked. It is equipped with solar panels, an automated docking system, and glass cockpit interfaces modeled after those used in the Boeing 787 Dreamliner. A single AJ10 engine provides the spacecraft's primary propulsion, while eight R-4D-11 engines, and six pods of custom reaction control system engines developed by Airbus, provide the spacecraft's secondary propulsion. Although compatible with other launch vehicles, Orion is primarily intended to launch atop a Space Launch System (SLS) rocket, with a tower launch escape system.
Orion was originally conceived in the early 2000s by Lockheed Martin as a proposal for the Crew Exploration Vehicle (CEV) to be used in NASA's Constellation program. Lockheed Martin's proposal defeated a competing proposal by Northrop Grumman and was selected by NASA in 2006 to be the CEV. Originally designed with a service module featuring a new "Orion Main Engine" and a pair of circular solar panels, the spacecraft was to be launched atop the Ares I rocket. Following the cancellation of the Constellation program in 2010, Orion was heavily redesigned for use in NASA's Journey to Mars initiative; later named Moon to Mars. The SLS replaced the Ares I as Orion's primary launch vehicle, and the service module was replaced with a design based on the European Space Agency's Automated Transfer Vehicle. A development version of Orion's CM was launched in 2014 during Exploration Flight Test-1, while at least four test articles have been produced. Orion was primarily designed by Lockheed Martin Space Systems in Littleton, Colorado. As of 2022, three flight-worthy Orion spacecraft are under construction, with one completed and an additional one ordered, for use in NASA's Artemis program.
The first completed unit, CM-002, was launched on November 16, 2022 on Artemis 1.
