What is Dark Ages Radio Explorer?
The '''Dark Ages Radio Explorer''' ('''DARE''') mission is a [[robotic spacecraft|lunar orbiter]] concept which will be used to identify the coming [[redshift]] from first [[hydrogen atom]]s just as the first stars began to produce light. DARE will use the [[redshift]]ed 21-cm transition line from [[neutral hydrogen]] (1420.00&nbsp;MHz emissions) to view and spot the formation of the first glowing objects of the universe. Also, this is the period ending of the [[Chronology of the universe#Dark Ages|Dark Ages of the universe]]. The orbiter will explore the universe as it was from around 80 million years to 420 million years after the [[Big Bang]]. The mission will deliver data of the formation of the first stars, the beginning of [[black hole]] accretions, and the [[reionization]] of the universe. [[Computer model]]s of [[galaxy formation]] will also be tested.<ref name=burns>{{Cite journal |doi=10.1016/j.asr.2011.10.014 |url=http://lunarscience.nasa.gov/wp-content/uploads/drupal/DARE_in_press.pdf |format=Free PDf download |title=Probing the first stars and black holes in the early Universe with the Dark Ages Radio Explorer (DARE) |date=2012 |last1=Burns |first1=Jack O. |last2=Lazio |first2=J. |last3=Bale |first3=S. |last4=Bowman |first4=J. |last5=Bradley |first5=R. |last6=Carilli |first6=C. |last7=Furlanetto |first7=S. |last8=Harker |first8=G. |last9=Loeb |first9=A. |last10=Pritchard |first10=J. |journal=Advances in Space Research |volume=49 |issue=3 |pages=433 |arxiv=1106.5194 |bibcode=2012AdSpR..49..433B |s2cid=56282298 }}{{Dead link|date=February 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref name=nasadare>{{cite web | title =DARE paper in Advances in Space Research now in press | publisher =NASA Lunar Science Institute | date =2012 | url =http://lunarscience.nasa.gov/articles/dark-ages-radio-explorer-in-press/ }}{{Dead link|date=February 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref name=colo> {{cite web | title =DARE Mission overview | publisher =University of Colorado
