Esrange

Esrange Space Center is a rocket range and research centre located about 40 kilometers east of the town of Kiruna in northern Sweden. It is a base for scientific research with high-altitude balloons, investigation of the aurora borealis, sounding rocket launches, and satellite tracking, among other things. Located 200 km north of the Arctic Circle and surrounded by a vast wilderness, its geographic location is ideal for many of these purposes.

Esrange was built in 1964 by ESRO, the European Space Research Organisation, which later became European Space Agency by merging with ELDO, the European Launcher Development Organisation. The first rocket launch from Esrange occurred on 19 November 1966.[1] In 1972, ownership was transferred to the newly started Swedish Space Corporation.

History

In the 1960s Esrange was established as an ESRO sounding rocket launching range located in Kiruna (Sweden).[2] This location was chosen because it was generally agreed that it was important to carry out a sounding rocket programme in the auroral zone, and for this reason it was essential that ESRO equip itself with a suitable range in the northern latitudes. Access to Kiruna was good by air, road and rail, and the launching range was relatively close to the town of Kiruna. Finally and perhaps decisively, Esrange could be located near Kiruna Geophysical Observatory (subsequently renamed to Swedish Institute of Space Physics). In 1972 ownership and operations of the range was transferred to the Swedish Space Corporation.

Name

The name of the facility was originally ESRANGE, which was an abbreviation for ESRO Sounding Rocket Launching Range.

When Swedish Space Corporation took over the range, its name became Esrange (with capital 'E' only).

Esrange Space Center is the name that is currently used for the facility.

Other ways to interpret the name over the years has been European Space and Sounding Rocket Range, and European Space Range.

Rocket activities

There had been Swedish rocket activities previously, mainly at Kronogård (18 launches in the period 1961–1964).[3] However, the rocket activity in Sweden did not gain thrust until after ESRO established Esrange in 1964.

During the period 1966–1972 ESRO launched more than 150 rockets from Esrange. Most of these were Centaure, Nike Apache, and Skua rockets reaching 100–220 km altitude. They supported many branches of European research, but the emphasis was on atmospheric and ionospheric research.

In 1972 the management of Esrange was transferred to the Swedish Space Corporation (SSC). Gradually the smaller rockets were complemented by larger rockets reaching higher altitudes, achieving weightlessness for a few minutes when the rocket is above the parts of the atmosphere giving an appreciable friction. Three main programmes, Texus, Maser, and Maxus currently dominate the rocket activities at Esrange and support microgravity research for ESA and DLR:

Programme Rocket motor Peak altitude Payload mass Microgravity time Period Launches Customers
Texus Skylark 7, VSB-30 250–300 km 330–400 kg 6 minutes 1977– 58 DLR and ESA
Maser Black Brant, Skylark 7, VSB-30 250–300 km 330–400 kg 6 minutes 1987– 15 ESA
Maxus Castor 4B 700–720 km 800 kg 12–13 minutes 1991– 8 ESA and DLR
Mini-Texus Nike Orion 120–150 km 160–200 kg 3–4 minutes 1993–1998 6 DLR and ESA
Rexus Improved Orion 80–110 km 100kg 2 minutes 1995– 30 DLR, ESA, ZARM
MAPHEUS Nike-Orion, VS-30, Improved Malemute/Improved Malemute 150-250 km - 6 minutes 2009- 13 DLR
SERA Cesaroni Pro 98-6G 5-10 km - - 2014- 4 CNES

SSC, jointly with DLR, introduced a new launch service with the Suborbital Express programme launched in 2019. Suborbital Express is now integrating the Maser microgravity programme.[4]

More than 500 rockets have been launched from Esrange since 1966. For information on individual rockets, see the List of rockets launched from Esrange.

Esrange has six launchers:

  • MAXUS launcher (used for the CASTOR 4B rocket)
  • MAN launcher (owned by DLR)
  • MRL Launcher (used for the Orion, Nike-Orion, Taurus-Orion, Nike-Black Brant V, Terrier-Black brant rockets)
  • Skylark launch tower (used for the VSB 30 rocket)
  • FFAR launcher (used for Folding Fin Aircraft Rockets)
  • SULO/VIPER launcher (used for Super Loki and VIPER rockets)

Balloon activities

Since 1974, more than 500 high-altitude balloons have been launched from Esrange for research purposes. The launch pad can handle balloons with volumes exceeding 1 million cubic meters.

Satellite services

The arctic latitude of Esrange makes it very suitable for communication with satellites in polar orbits. Esrange Satellite Station is part of a global network with stations in Canada, Alaska, Hawaii, Chile and Australia. This global network is managed from Esrange.

Esrange Space Center satellite station emphasizes on data acquisition and processing for remote sensing and scientific missions as well as TT&C support. The station is often used in combination with SSC's Inuvik Satellite Station in northern Canada, to increase coverage opportunities for polar orbiting missions.

Esrange Space Center satellite station includes six independent Telemetry Tracking & Command (TT&C) systems in S-Band (one with receive capability also in the UHF-Band), six multi-frequency receive antenna systems in S/X-Band and an operational building which houses reception system electronics and data processing equipment. Satellite services at Esrange began in 1978.

Satellite control services

A number of telecommunication satellites have been controlled through Esrange:

Most research satellites of the Swedish space programme have received control commands through Esrange:

The exception was controlled from SSC's laboratories in Solna outside Stockholm:

Ground station services

Data have been received at Esrange from more than 50 satellites, including SPOT 1–5, Landsat 2–7, ERS-1–2 and Envisat.

Satellite launch capability

Ideas to use Esrange Space Center for orbital launches has existed since the inauguration of the base in 1966, then in the vision of ESRO. As new smaller launcher projects started to emerge in the beginning of the new millennia, SSC started to form new ideas to use these to obtain an orbital capability.

On October 14, 2020, Matilda Ernkrans, the Swedish Space Minister, announced the decision of the Swedish government to establish capability to launch small satellites from Esrange Space Center in northern Sweden.[5]

The orbital launch site, LC-3, was inaugurated on 13 January 2023 as the ribbon was cut by the Swedish king Carl XVI Gustaf, prime minister Ulf Kristersson together with head commissioner President Ursula Von der Leyen.[6] There are currently plans for an orbital launch at the end of 2023.

Impact
A vast uninhabited area north of the range is used as an area where the sounding rockets can land. Spread throughout this area are small shelters, like the one shown in this picture. When a launch campaign is planned, people are asked to visit such shelters and listen to the radio. This shelter is at Vassejávri, around 10 km west of Järämä (Sweden).
Interior of such a shelter

The area of the site is traditional land of the Sami people, particularly for reindeer herding. Shelters have been established for people in the surrounding area to take cover during launches. Increased industrial, military and aeronautic activity in the region has been viewed critically by Sami people.[7][8]
