Fallen alien-hunting Arecibo Observatory will be rebuilt as Puerto Rico commits $8 million to its reconstruction
- The Arecibo Observatory in Puerto Rico collapsed on December 1
- A cable holding up a platform snapped and the telescope was destroyed
- This week, Puerto Rico’s governor signed an executive order to rebuild it
- Approximately $8 million has been committed to the project
- This includes cleaning up the debris and designing a new telescope
The Arecibo Observatory collapsed earlier this month, ending its 57 year reign that devastated scientists around the world.
Puerto Rico Governor Wanda Vázquez has now signed an executive order approving $8 million to help rebuild the renowned telescope.
The order states reconstructing Arecibo is ‘a matter of public policy,’ along with declaring the observatory site a historic zone.
The $8 million is set to be used for removing and disposing of the debris and the design of the new telescope.

‘The government of Puerto Rico is convinced that the collapse of the radio telescope brings a great opportunity to redesign it taking into consideration the lessons learned and the recommendations from the scientific community to make it relevant for decades,’ said Vázquez Garced, through La Fortaleza’s official website.
Arecibo collapsed December 1 when a cable holding up a 900-ton receiver platform snapped around 8am local time that morning and sent the massive structure hurling onto the reflector dish more than 400 feet below.
Arecibo Observatory suffered another failure in August when an auxiliary cable broke that resulted in a 100-foot gash on the 1,000-foot-wide dish and damaged the receiver platform that hung above it.
Then a main cable failed in early November that sealed the iconic telescope’s fate – officials were set to shut it down after 57 years of service.

Arecibo Observatory is famous for detecting whirling pulsars, capturing geological features of Mars and helping astronomers discover the near-Earth asteroid Bennu, along with making an appearance in the 1995 James Bond film GoldenEye.
The giant telescope was also used in programs that search for extraterrestrial intelligence (SETI) because its location provided scientists access to one-third of the cosmos.
The recent collapse has left many experts stunned who had relied on what was until recently the largest radio telescope in the world.
‘It sounded like a rumble. I knew exactly what it was,’ said Jonathan Friedman, who worked for 26 years as a senior research associate at the observatory and still lives near it.
‘I was screaming. Personally, I was out of control…. I don’t have words to express it. It’s a very deep, terrible feeling.’

After hearing the distant roar, Friedman said he ran up a small hill near his home and saw a thick cloud of dust hanging over the location of the telescope – confirming his suspicions and greatest fear.
SETI Institute gave the telescope a personal farewell on November 20 when Arecibo was only set to be ‘taken apart and tucked away.’
Seth Shostak, Senior Astronomert wrote: ‘Losing Arecibo is like losing a big brother. While life will continue, something powerful and profoundly wonderful is gone.’
ARECIBO OBSERVATORY HISTORY
1963: Arecibo Ionospheric Observatory Commissioned for service on November 1 for $9.7 million.
1965: One of its first accomplishments was establishing the rotation rate of Mercury, which turned out to be 59 days rather than the previously estimated 88 days.
1968: Sporadic radio pulses from the direction of the Crab Nebula supernova remnant found at Green Bank were shown by Arecibo to come from a 33-ms period pulsar situated at the center of the nebula.
1974: New high precision surface reflector installed, planetary radar transmitter installed.
1974: The first pulsar in a binary system was discovered, leading to important confirmation of Einstein’s theory of general relativity and a Nobel Prize 1993 for astronomers Russell Hulse and Joseph Taylor.
1974: On 16 November, the ‘Arecibo message’ was broadcast into space toward the globular star cluster M13 25,000 light years away.
The message’s main purpose was to demonstrate the capabilities of newly installed equipment in the upgraded radio telescope and was an attempt to contact extraterrestrial intelligence.
1979: A large, anomalous travelling ionospheric disturbance (that is, an upper atmosphere wave) moving southeast to northwest was detected in the early morning hours – something researchers had never before witnessed. Data helped define the probable cause as an air nuclear blast over the Indian Ocean.
1981: First radar maps of the geologic surface of Venus are produced.
1982: The discovery of strong ‘megamaser’ emission from the hydroxyl (OH) molecule in the starburst galaxy Arp 220 (IC 4553).
1982: The discovery of millisecond pulsars, which rotate several hundred times per second. This demonstrated the existence of two classes of pulsars – the millisecond pulsars and the slower-rotating pulsars, which rotate about once per second.
1989: The first measurement of hydrogen escape flux from Earth is presented, based on velocity distribution measurements of the hydrogen airglow emission in the upper atmosphere.
Early 90s: The first planets outside the solar system were discovered around Pulsar B1257+12, a rapidly rotating pulsar with three Earth-like planets in orbit.
1992: In October, ice is discovered in shadowed craters at Mercury’s north pole. Later observations show ice in south pole craters as well.
1996: A layer of helium ions is shown to be a common, but previously unrecognised feature in the low-latitude ionosphere near 600 km.
1998: Arecibo Observatory ‘found’ the Solar and Heliospheric Observatory (SOHO) spacecraft on July 28, after it lost communications with European Space Agency and NASA,. by bouncing a radar signal off the satellite. SOHO’s mission was resumed and continues to produce data today.
May 2000: Radar Observations of Asteroid 216 Kleopatra reveal a ‘dog bone’ shaped metal-rich object.
September 2000: Discovery that 2000 DP107 was the first near-Earth asteroid identified by radar as a binary system. The primary is roughly spherical with a diameter of a half mile and the smaller secondary, which orbits it in 1.8 days, is about 1000 feet.
2003: Evidence for hydrocarbon lakes on the Saturn satellite Titan is established using the Observatory planetary radar.
April 2004: Installation of the Arecibo L-band Feed Array, enabling a wide variety of astronomical surveys including discovering pulsars, mapping the gas in our Galaxy, and searches for other galaxies.
2005-2012: Radar imaging of Mars reveals lava flows and near-surface geologic features not seen in visible images. This provides new insights into Mars surface geology.
2006: Search for water ice in the permanent shadow of the lunar Shackleton Crater disputes evidence for water ice on the lunar surface.
October 2006: Radar images of the south pole of the moon reveal no evidence for thick deposits of ice.
November 2006: Radar images of binary asteroid (66391) 1999 KW4 in May 2001 and again in June 2002 reveal exotic physical and dynamical properties which may be common among near-Earth binaries.
March 2007: Radar images of Mercury reveal features to be studied further by the Messenger spacecraft over the next several years.
2007: The near-Earth asteroid 2005 PH5 was observed to be increasing in spin rate, due to non-uniform absorption and emission of solar radiation.
2007: Previously undetected radio lines of the molecule hydrogen cyanide (HCN), and the presence of the molecule methanimine (CH2NH), were recently discovered in the distant ‘starburst galaxy’ Arp 220.
February 2008: Discovery of the first triple asteroid system among the near-Earth asteroids. The asteroid, 2001 SN263, is about 1.5 miles in diameter, with two moons orbiting it.
2008–2012: Observations discover a radio outburst in the nearby galaxy NGC 660, ten times brighter than a radio supernova.
2011: Observations of brown dwarfs find the coldest star to show radio emission.
November 2011: Radar imaging of near-Earth asteroid 2005 YU55, which made a very close flyby. This dark, spheroidal asteroid was found to be about 1,148 feet in diameter.
2012: An ion-neutral chemistry model is developed to successfully describe thin layers of neutral metal atoms at above 62 miles altitudes.
